I'm going to help in conversion from B&G MS to VEMS in friend's n/a Jetta 16v.
- 4 cyl fuel injection, Hi-Z injectors
- Ignition with distributor, probably will go to wasted spark later
- PWM controlled idle valve
- 1xWBo2
- trigger from hall in distributor, 1 pulse/cylinder
Shopping list:
- 1 x GenBoard v3.2
- 1 x Econoseal36-PCB
- 1 x Econoseal36-Wire
- 1 x Econoseal18-PCB
- 1 x Econoseal18-Wire
- 1 x Alubos1600
- 1 x Alubos EC frontplate transparant
- 1 x Alubos Endplate transparant
- 2 x Alubos gasket
- 9 x FETs Injector driver, WBO2 heater driver (FQFP..)
- 5 x Ignition driver (IGBT)
- 1 x Ignition driver insulator sheet
- 1 x 2.5 bar MAP sensor
- 1 x Wideband connector
Information hunting
Let's assume one who never before has browsed through wiki has just got his V3.2 order. He might end up wondering what to do next? Does he need to solder something by hand? A little searching brings following pages:
- BuildProcedures/SectionThree
- GenBoard/Manual/InitialTesting/VerThree contains some information about the hardware to check
- GenBoard/VerThree/Testing contains same kind of information
- GenBoard/Manual/WBSensorControllerCompleting
- Some information is collected to the StepByStep page
So there is something to start. Maybe a proper step-by-step guid is needed, I'll try collecting the issues to a separate page from this exercise.

It's alive. Engine was running yesterday, board was only delivering fuel. Latest config files:

Problem below was solved by updating a perl. With perl v5.8.6 make_ini.pl works smoothly.
Yesterday we made some initial tests in the car. MT configuration started to look somehow acceptable after a couple of hours, basically using old configuration from B&G MS. However TPS readings were not ok, values were either 16% at idle or by adding some throttle value jumped directly to 100%. In the LCD TPS values were ok.

Some problems with perl. I use a activestate perl under Win: This is perl, v5.6.1 built for MSWin32-x86-multi-thread
When trying to run perl bin\make_ini.pl global.h doc\megatune\config.xml doc\megatune\vemsv3.ini I get an error message\n
"strict" is not defined in %XML::Simple::EXPORT_TAGS at C:/APPS/Perl/lib/Exporter/Heavy.pm line 75
Exporter::heavy_export('XML::Simple', 'main', ':strict') called at C:/APPS/Perl/lib/Exporter.pm line 45

Can't continue after import errors at bin\make_ini.pl line 10

I tried to download XML-Simple from activestate and installed it ppm install XML-Simple.ppd without any warnings etc. but obviously something is still wrong. Any hints?

Board/case assembly is now mostly completed after some not-so-active period.
- Partially commented configuration files added here. These are not in any proper shape yet, mostly copied from GRM's config but will update once I get to the some real business.

Completing of the controller begins.
Although board has a most of the parts already soldered on it, a few components still needs to soldered by hand.
- Injector driver FETs (TO220)
- Ingition IGBTs (TO220)
- WideBand LSU4 sensor heater driver (we use TO220 FET, same type as for injector drivers; except the WBO2 channel has no onboard place for flyback diodes)
There are also several items to check before even thinking to plug the board to the car.
- items to check listed here..

Ordered items arrived
more details will follow..
